\u00a0\n\u00a0\nI am certain that the supplement shelf of any ambitious athlete might look better stocked than the drug closet of most ICUs. Gotcha!Because supplements are that popular among many people it is reasonable to question which one of them are really useful?\nMost supplements come for a price. That's because behind protein powders and vitamin c capsules is a huge industry, dominated by very aggressive marketing, daring promises and much bullshit.\n\u00a0\nTo save your money and eliminate some false promises I worked out this post. All supplements here are backed by science, tested by myself for a long period of time and most important - I don't want to sell you anything, unlike all big brands.\n\u00a0\nAlright, let's take a close look at the substances that made it into the top ten of useful supplements!\n\u00a0\n\n\u00a0\n\u00a0\nWhich supplements are useful? - the 'Must-Takes'\nVitamin D3\nVitamin D3, also known as the sun hormone,*\u00a0 is made by sunlight reaching your skin.\nBut there lies a big problem. Many folks in the northern hemisphere get way too less direct sunlight at their skin, especially when the days get shorter. That's why it shouldn't be a miracle why many of us don't even reach the bare minimum of what is considered as optimal levels \nAn optimal supply with vitamin d is very important because this substance infliences a LOT of bodiliy processes.\nVitamin D is most important for high testosterone leves, a balanced immune system, strong bones, and even your cognitive function.\nI think I speak for all of us if I say - you don't wanna mess with these guys!\n\u00a0\nMy recommendation for every healthy adult would be 2.000-4.000 IU per day.\u00a0Take this dose at any daytime you prefer, but together with your other supplements. Especially the combination with vitamin k2 and calcium is very beneficial.\n\u00a0\n\u00a0\nVitamin K\nThis vitamin consistes of two different vitamins - K1 and K2:\n\nYou can find Vitamin K1 in all leafy greens. If you are eating enough veggies a day or many green salads you should be fine with this guy.Vitamin K1's function is to obtain the health of your blood vessels - especially their elasticity.\nVitamin K2 is comparedly new in the world of science. It can be found in guts and fermented products.K2 has nothing to do with your blood vessels. Instead it supports strong bones.\n\nWhile Vitamin K1 is easily taken in with your normal nutrition if you don\u00c4t just eat meat, K2 can be hard to find in our modern, western nutrition. Guts and fermented products as natto aren't that common.\n\u00a0\nA great point is that vitamin K2 and D3 work synergistically to support strong and healthy bones. They even amplifiy each other.\nPlus, K2 keeps calcium away from the vessel's inner wall to prevent arteriosclerosis. That's why the combo of these 3 can be very useful.\n\u00a0\nTake around 50-100 mcg\u00a0 of K1 per day, if you really need it. Of K2 I would recommend taking around 100-200 mcg per day*. Take it alongside your vitamin d and bone problems should bone issues should be no problems for you as an athlete.\n\u00a0\n\u00a0\nFish oil\n\nFish oil consists mainly of omega-3-fatty-acids. I think everyone heard of these guys somewhere.\nIt is true that these special fatty acids can improve many bodily functions. A few to stand out are your cardiovascular health, and inflammations.\nThe main issue is that most of us eat way too less fat fish - not to mention that most of them contain alarming levels of heavy metals. On paper you should eat around 1kg of salmon per week to eat enough omega-3's.I am out when it comes to this number - I would have to sell my ass to buy salmon! :-D\u00a0\n\u00a0\nWhen supplementing omega-3's it is important to have a look at their content of EPA & DHA. Per day you should take around 1g of fish oil* or 250mg of DHA & EPA combined.\n\u00a0\nDon't make the mistake and take linseed oil, like many brands advertise it. It contains a fatty-acid named ALA. And your body can make DHA and EPA from ALA. Sounds great, isn't it? That's what the brands tell you - BUT most of us can only convert a tiny part of the whole ALA to EPA &DHA. Therefore to get 250mg you would have to drink around 50ml-100ml per day.\n\u00a0\nDoesn't sound that convincing, isn't it? And the saved 800 calories can be invested more wisely - in sushi for example.\n\u00a0\n\u00a0\nCreatine\nCreatine* is an aminoacid commonly found in your body and one of the best researched supplement there is.\n\u00a0\nCreatine's main job is to quickly supply your muscles with energy when it is needed. But it also enhances congnitive functions.\u00a0\nLet me tell you one thing right here - creatin doesn't kill kidneys. That is a misunderstood myth by people who don't get the difference between creatine, creatinine and what role they play for your kidney. \n\u00a0\nTake creatine not treatementwise. That is so 1980 - and also scientifically proven useless. Instead, take around 20g per week. I would take 5g 4 times a week before or after your days workout.\nThe exact time doesn't matter because your body stores it away anyways. The only thing I wouldn't do is to take 20g of creatine sunday at 9pm when you realized you forgot to take it the whole week. :-D\n\u00a0\n\u00a0\n\u00a0\nWhich supplements are useful? - the 'Nice-To-Haves'\nProtein powder\n\nProtein powder can be useful, but also wasted money. Much depends on your lifestyle.\nThe question is - do you need additional protein?Check your macros for that. Check how mich\u00a0 protein you should eat per day and how much you really manage to eat.\n\u00a0\nProtein powders differ in the time how fast your body can digest them. There are quicker and slower varaiants all with their very own uses.\n\u00a0\nOne of the biggest benefits of these colorful powders is their simplicity and awesome taste. For me there is nothing more gorgeous than the ritual of a tasty PWO-Shake after a successful session. Seems to be something like my cigarette afterwards. :-D\nDecide for yourself if you can benfit from such a ritual, have problems getting sufficient protein in with your regular diet, or you like to exchange sweets.\n\u00a0\nMy favorite protein powders are the whey by MyProtein*, ot the casein byn MyProtein* as well as the all-in-one-protein by More Nutrition*.\n\u00a0\n\u00a0\nMagnesium citrate\nI'm sure you know magnesium, well. Many people take the sweet effervescents. There is one problem with that - most of the time they contain cheap magnesium oxide. And Your body is horrible at absorbing this particular substance.\nMagnesium citrate* on the other hand can be absorbed way better. That way the magnesium you pour into yourself gets where it is needed - and doesn't remain in your intestines.\n\u00a0\nYour body need magnesium to build a lot of hormones and for the nervous system to function properly.\nI would supplement this substance if you don't eat enough per your regular diet or you simply need more of it. This is the case for all athletes, pregnants and smokers. You should take around 400mg per day.\nIf you are unsure about the exact amount you eat per day - throw an example day of your life into a nutritional calculator. That should give you an approximate value.\n\u00a0\n\u00a0\nGelatine\nGelatine as a supplement*?! Yes, really, I'm serious!\nGelatine is an awesome supplement for healthy joints and connective tissues - unfortunately, noone knows it as that.\n\u00a0\nGelatine solves one issue caused by modern eating habits.\u00a0We don't eat any connective tissues, like cartilage, bones or tendons. Most of our meats are lean. But - connective tissues are built of very special aminoacids.\n\u00a0\nThat's why gelatine can help your joints. It provides kollagen, as well as the amino acids prolin and gylcine. Plus, it is supercheap.\nIf you wanna read more about gelatine check my post about this supplement out.\n\u00a0\n\u00a0\n\n\u00a0\n\u00a0\n\u00a0\nWhich supplements are useful? - the 'It-Depends'\nCaffeine and L-Theanine\n\nCaffeine* - which werido doesn't know and deeply love this black goodness? While coffee was close to the devil 100 years ago, nowadays modern society wouldn't function without its steady supply.\nCaffeine is a well-researched performance-enhancing substance and stubstance of choice for many people to push themselves a bit. The only issue with that is - you accustomize yourself to caffeine quickly. It is like with any other drug - abuse is the wrong way to go.\n\u00a0\nThat's why it makes sense to stay away from coffee every 2-3 months. I go more in detail about caffeine in this short infopost.\n\u00a0\nBefore working out take about 200-400mg of caffeine - that should get he job done. I like to combine it with the same amount of l-theanine to reduce extreme hyperactivity caused by such doses of caffeine. L-theanine* calms everthing down a bit - also know in the research world as calm focus.\nGive this combo a try - I really enjoy it. Especially if you are sensitive or don't like the effect of caffeine that much.\n\u00a0\n\u00a0\nMelatonin\nThis one is a great supplement to get a good nights rest. I've experimented with it for years now.\nMelatonin is a hormone found in your body and heavily influenced by light. It is one factor that tells the body: "Ey dude, it's getting late - let's switch the lights off!"\n\u00a0\nThe problem regarding melatonin secretion within your body is that blue light inhibits it. And blue light is what most screens, bulbs (and daylight, too) emit. They are really effective at surpressing melatonin.\nEven a small red LED of your TV can surpress meltonin by 15%. A fuckin small LED :-D You can read more about melatonin in this infopost.\n\u00a0\nEspecially when you suffer from issues sleeping in, or are jetlagged, or working shifts, I can recommend the combination of 1,5g-3g of melatonin and 200mg passionflower.\n\u00a0\n\nWon't I stay weak without BCAAs?! Do I survive a day without Beta-Alanine?!\nComplete Nonsense and a waste of your money\nBCAAs, EAAs, Testo booster and fat burners earned their place to be named before any other bullshit substances. Those few are useless for everyone. Ok maybe not for the marketers selling them - they fill their pockets.\n\u00a0\n\nBCAAs and EAAs are incomplete and isolated aminoacids and can be replaced by any whey.\u00a0\nThe best testosterone boosters there are, are an healthy nutrition, strength training, a good night's sleep and sex.The only other thing that can increase your testosterone significantly - is injected testosterone. Wow! That said - check that the basics are in place and stay away from daring marketing lies (and of course anabolics).\nThe best fatburner are training, movement, a balanced diet and stop eating like an asshole.Fat loss works that easy - not because of raspberry ketones...I only know of one substance that can burn fat in huge amounts - DNP. BUT - don't get tempted and try it. There is a huge risk of burning metabolically from the inside out.\nBe skeptic of new supplements, aggressively marketed novelties and shortcuts to 200kg of lean muscle mass in 20 days.Checke every supplement you wanna take on examine or over here. This will save you a lot of money.\n\n\u00a0\nTake stock\nMy advice would be to take stock of all the supplements you use.\nBecause there are many supplements, which effects are non-existent or very small. First off you should check if your basic are in place. No supplement there is can help People without proper sleep, who are on a strict diet, and working out like insane and are stressed out as fuck.\n\u00a0\n\u00a0\n\n\u00a0\nSources and further reading:\nA great site to check all your supplements is Examine. It is a scientific page, easily written for the average joe. The team over there does great work and tries to cut out the bullshit plagueing this industry.\n\nYou can find much more information about Vitamin D3 in these two articles:This one describes the vitamin itsself and this article presents the newest research about it, \u00a0plus how you should supplement vitamin d optimally.\nOn this page of examine and this Wikipedia article you can learn everything you wanna know (and don't wann know) about Vitamin K.\nThere is a great and very detialled Wikipedia article, about omega-3-fatty-acids and fish oils, as well as an excellent Examine post.
